Postfix stable release 2.9.5,
and legacy releases 2.8.13, 2.7.12, 2.6.18 are available.
They contain fixes and workarounds that are also part of
Postfix 2.10.
Postfix 2.9 only:
False error (missing "]" character) when a reject_{rhs,dns}bl_*
or permit_{rhs,dns}wl_* reply pattern started with "[".
Reported by Martijn Brinkers.
Postfix 2.8 and later:
The postscreen_access_list feature failed to ignore case in
the first character of a command (e.g., permit, reject, etc.).
Reported by Francis Picabia. (This fix is incorrectly listed
in the HISTORY files of earlier releases, and will be removed
with a future patch.)
All supported releases:
Strip the datalink suffix (e.g., %eth0) from IPv6 addresses
returned by the system getaddrinfo() routine. Such suffixes
break the default mynetworks value, the Postfix SMTP server's
reverse/forward DNS name/address mapping check,
and possibly more.
To eliminate the possibility of collisions with connection
cache lookup keys, the Postfix LDAP client now computes
those lookup keys by joining the number-valued connection
properties with ASCII null, just like it already did with
the string-valued connection properties.
There was a memory leak during one-time TLS library
initialization (introduced with Postfix 2.5).
Reported by Coverity.
There was a memory leak in the unused oqmgr(8) program
(introduced with Postfix 2.3).
Reported by Coverity.
